[QUOTE="D.Camilleri, post: 975925, member: 2567"] I am loading my 338 rum to 3.670 with 300 gr berger otm in front of 90 gr of H-1000 and it is yielding 2850 fps confirmed in drop to 1250 yds. This is a pretty hot load in my gun and my primer pockets aren't lasting a real long time. I had a bunch of Federal nickel brass and it is very soft and the primer pockets are getting loose after one firing. I also have quite a bit of factory federal ammo loaded with 225 nos accubonds and they are a bit hotter than advertised, but not as hot as my handloads. The biggest difference is the C.O.L. Seating the bullet out further drops the pressure and allows more powder. My barrel is a broughton 5c with a 9.3 twist, and it could have something to do with the velocity. I would like to try some Rel 33 to see if there is a little more on the table though. My buddy has a factory remmy xcr and gets right around 2700 with 91 grains of H-1000 and sierra match kings. We have shot side by side and he has to dial in quite a bit more elevation than me. The berger otm's don't seem to be sensitive to seating depth. I picked a length that was the longest that would feed as a repeater in my action (single shot is no good when hunting in the land of the grizzly) [/QUOTE]
